(F)3x-2(g)2x+1
Your subtracting to subtract the two x
(3x-2)-(2x+1)
The parenthesis is to know they are separate and not a negative number not subtract

Answer:

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

We have f(x) = 3x - 2 and g(x) = 2x + 1. Substitute:

(f - g)(x) = (3x - 2) - (2x + 1)

(f - g)(x) = 3x - 2 - 2x - 1 <em>combine like terms</em>

(f - g)(x) = (3x - 2x) + (-2 - 1)

(f - g)(x) = x - 3

Which expression is a difference of squares with a factor of 5x − 8? 25x2 − 16 25x2 16 25x2 − 64 25x2 64.

SpyIntel [72]

The product of the factors (5x − 8) and (5x + 8) is 25x² − 64. Then the correct option is C.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

One factor of the polynomial is given which is 5x − 8.

Then the polynomial will be

Let the other factor be 5x + 8

Then their product will be

(5x − 8)(5x + 8)

(5x)² − 8²

25x² − 64

rewona [7]

Answer:

2 x² - 6x -5

Step-by-step explanation:

<u><em>Expansion:-</em></u>

Given that the expression

(8x²-7x-2)-(6x²-x+3)

= 8x² - 6x² - 7x +x -2 -3

= 2 x² - 6x -5

The width,w, of a rectangular garden is X -2 the area of the garden is X^3-2X-4 what is an expression for the length of the gard

slamgirl [31]

$A=lw \Rightarrow l=\frac{A}{w}$
A - area, l - length, w - width

$w=x-2 \\
A=x^3-2x-4 \\ \\
l=\frac{x^3-2x-4}{x-2}=\frac{x^3-2x^2+2x^2-4x+2x-4}{x-2}=\frac{x^2(x-2)+2x(x-2)+2(x-2)}{x-2}= \\
=\frac{(x^2+2x+2)(x-2)}{x-2}=x^2+2x+2$

The answer is D. x²+2x+2.

Subtract:

Shtirlitz [24]

Answer:

Step-by-step explanation:

(3x³ - 10x² + 13x) - (5x³ + 4x² - 9x)

3x³ - 10x² + 13x - 5x³ - 4x² + 9x Change all terms after the subtraction sign to

the opposite sign (definition of Subtraction)

(3x³ - 5x³) + (-10x² - 4x²) + (13x + 9x) Group like terms together

-2x³ - 14x² + 22x
